ADJUSTABLE GANG-FRAME For. CULTIVATORS.

Patented Feb. 1, 1916.

Application filed April '7, 1915. Serial No. 19,667.

To all whom it may concern} Be it known that I, HENRY J. KUHLrmN, a citizen of the United States of America,

' and a resident of Golesburg, Delaware gang-frames for cultivators,

county, Iowa, have invented certain new and useful Improvements in Adjustable Gang Frames for Cultivators, of which the following is a specification.

My invention relates to improvements in and the object of my improvements is to provide sectional gang-frames so jointed and connected to the main frame, adjustably, as will permit of most effective use in being shifted laterally or moved up or down as a whole or in certain parts, to secure the required actions when desired. This object I have accomplished by the mechanism which is hereinafter described and claimed, and which is illustrated in the accompanying drawings,

. in which Figure 1 is a side elevation of a culti vator containing my improved gang-frames, with parts removed or broken away. Fig. 2 is an upper plan view of said machine. Fig. 3 is an enlarged detail side elevation of the jointed connections between the forward and intermediate sections of one of thegang-frames. Fig. 4 is a side elevation of the reverse of Fig. 3. Fig. 5 is an enlarged top plan view of the'parts shown in Figs. 3 and 4. Fig. 6 is an elevation of the said partstaken from the rear obliquely. Fig. 7 is a detail perspective view, enlarged, of the parts of the lever actuated shifting-means of said device. I

Similar numerals of reference denote corresponding parts throughout the several views. Q

The cultivator shown has a tongue 6 mounted in the main-frame bars 7 the latter extending rearwardly and parallel to a location in the rear of the pair of carrying wheels 48, the latter being rotatably mounted on the spindles of the bowed axle 49, whose bowed part is medially secured to the rear part of the tongue. A. cross-bar 5 secured medially to the tongue has its oppositely extended parts secured to the frameparts 7 and dropped to provide spindles upon which are mounted the rock-bodies 4, which, with the pivot-bolts 3, form universal couplings whereby the forward parts 12 of the gang-frame sections are pivotally the parts shown in said connected to said spindles for both lateral Each gang-frame comprises the sections- 12, and 11, which have the shovels 13, 1'4 and 15 mounted in echelon therein in proper relation laterally and longitudinally, so that the middle shovel 14 is under the axis of and between the carrying-wheels,

with the shovels 13 and 15 located forwardly and rearwardly respectively of said axis. The forward gang-frame sectlon is made up of the rigidly connected rearwardly divergent bars'l and 2, rigidly spaced and secured attheir rear ends by a cross-bar hung between ears 33 and on pivot bolts '34. Under the cross-bar 33 another cross-bar 31 is pivotally connected at its upturned ends to said bars 1 and 2 by means of pintle-bolts 44 to-rock up and down and has a diskshaped part 29 projecting horizontally therefrom, as shown in Fig. 3. The bar 11 of the rear gang-frame section has a similar disk-shaped part 28 on its forward end, which overlies the other disk 29 in registration, and both disks are centrally orificed to receive a pintle-bolt 37, whereby the gang-frame sections are pivotally connected to swing laterally relative to each other.

The rear'part of the bar 2 has a socket 63 in which is pivotally mounted the lower end of an arm 24 which is bent overhorizontally and rearwardly to overhang the forward part of said bar 11 and orificed to seat the upper end of a headed bolt 25 which-is passed downwardly and slidably through a bearing 27 on the bar 11. Said bolt extends downwardly a distance below the bar '11 and has an adjustable stop-nut on its threaded lower end,while a coiled compres- 45 and in whose centralhollow' is secured a depending hanger or shank 40, upon whose lower end the forward shovel 13 is detachably mounted. A stirrup 39 is also mounted on the rear end of said bar 1. The numeral 35 denotes an upwardly-curved arm secured .by a set-screw 11 on the shank 40 and is at likewise secured on a shank depending from its rear part. .The rear end of the bar 11 is forked, with a disk-shaped part 55 of a rearwardly extending bar 12 seated pivotally on a pintle 56 between the forks. The disk upon the pintle-blt 56.

55 has a downwardly-orificed forwardlyprojecting finger, with a set-screw 57 passed through its orifice to engage the top of the bar 11, whereby the obliquity of the bar 12 may be adjusted, the disk then being rigidly clamped in said forks by means of the nut I On the rear end of each frame-bar 7 is a depending hanger 8 having its lower end offset and provided with an opening in which the rear end of thearm 12 is movably seated vto rock up and down when the gang-frame is moved up and down, and having .an adjustablebolt 10 set in'one or other of the'orifices 9 whereby an 7 adjustment vertically may be made.

I have adopted the following, means for shifting the gang-frames laterally, or up and down: A pair of levers 22 are used for thispurpose, each lever being mounted to swing either up and down or sidewise. Each lever is pivoted on a pintle 62 to aracksector 54,-the latter being integral with a cylindrical body 53-having a vertical slot 58 through which. thelever ispassedforwardly. The forward end of the lever has a row of orifices 21 in either of which one end. of a chain 23 is adjustably secured,lthe lower end of. the chain beingsecured tothe rear part of the bar 1. The lever has a finger-piece and movable spring-controlled detent which may be adjustably engaged with any of the teeth-on said sector. Referring nowv to said F i g."7, the lower solid part of thezcylinder 53 is centrally vertically orificed to seat the headed shaft 18, which extends downwardly through a registering central orifice in a cylindrical bearing-body 61 fiXedon an end of a cross-bar 61 mounted onthe rear part of said tongue 6. The shaft '18. is squared. at 59 to interlock with the cylinder 53, but is rotatable in'the bearing-body 61, but is provided with a lock-nut 60 to retain it in said seats. The shaft 18 has an offset crank-part 17 whose depending pin or off set end is seated rotatably and slidably in a bearing 16 on said gang-frame bar 2. The levers 22 may be operated from the drivers seat conjointly with the drivers stirrups 39 in the management and control of said gang-frames. Either lever may be rocked vertically to cause its chain-connection 23 to raise or lower the forward gang-frame section 1-2, the pivotally connected gangframe section 11 and its rearwardly-projecting bar 12 being also raised or lowered, the bar 12 being fulcrumed in the bearing 9. The pivotally-connected sections thus are, when in their lowered positions shown in Fig. 1, suspended with their shovels in the same depth in the ground, but when necessary for the forward shovel 13 to jump a hill of corn or the like, the lever may be employed to swing up the section 12, whereby the forward end of the section 11 is rocked up enough to lift the shovel 13 out of'the ground without entirely removing the other shovels 14: and 15 from the soil which thus may work along their rows without interruption. When the section l2 is elevated, the bearing 16 slides'upon the part 17 of the crank-shaft 18 without interference. The spring 26 acts upon the frame-bar 11 to normally keep it level except when swung upwardlyby the action of said lever on the bars 1.2 and connections, which maintains all the shovels in their desired positions The adjustable connection between the bars 11 and 12 also allows such relative adjustment of the rear part of the frame 11 as will cause the rear shovel 15 to properly act and be removed from the ground. Since the le- 7 ver 22 is, with its supporting-body 53, adapted to be rocked horizontally on the bearing 61, the crank-shaft 18 is rocked thereby to shift the gang-frame sections laterally, and since the crank-connection is with the forward section 12, the arc of movement of the forward shovel 13is greater than those of the othershovels, so that the driver may more easily control same'in sidewise move ments and with larger scope of play.
